Possible low fuel pressure. Turn the key on and off a couple of times and see if it will not start better. You may have a weak pump or a bad pressure regulator.

You need to have it scanned for codes for the check engine light. Don't worry about the VSC, and TRAC Off lights, THey are on because the Check engine light is on. Once you clear the code for the check engine light the other two lights will go off.

Helpful information.

By the way, It is VERY hard to remove the TOP bolt. I ended up removing the Battery and 2 Air hoses to be able to access it and then apply enough torque to get it out. A regular ratchet and a pipe aided in applying enough torque to move that bolt and then remove it. There is a diagram that shows the location of the top bolt (it is above the bottom bolt but located on the OPPOSITE side.
This diagram of the bolt placement will help, check this link:

if there is a switch, the owner's manual may have that information, you could also call the dealership, and ask to speak to the service manager, they should know and have info for you immediately, or they will take your info,look into it and call you back.This could be a stretch but maybe a recall problem you are unaware of, or it could just be a fuel pump.

yaw rate sensors require calibration. I wouldn't advise you do this yourself.

What happened? Same thing happened to my chevy cavalier and it turned out to be the gasoline pump. It happened after 15 months again. Too bad its my wife's car, otherwise I would have gotten another Scion XB.

Did you look at a wiring diagram to see what all is involved in those circuit's ? The fuse is GOOD ? 10 amp tail lamp fuse is good , but is there Battery + voltage there ? With a volt meter or test light check for B+ voltage on both sides of the fuse . Both the dash and tail lights get B+ voltage from the head lamp switch . You can find a wiring diagram here http://www.bbbind.com/free_tsb.html How to Use Multimeter to Troubleshoot Common Problems

If the check engine light is on it will usually disable the traction and VSC as a safety feature built into the vehicles computer program. Have the codes scanned to determine what the computer has stored in its memory as a fault resulting in these lights to be illuminated and repair as necessary. Sometimes it may be an intermittant issue causing this problem and just clearing the codes will reset all the lights and continue driving to see if the problem re-occurs. If it does, have the vehicle serviced for the problem

It might be in the ignition sensor. Most cars have a sensor that will not let the doors lock with they key in the ignition.

There is a bolt on the bottom of the alt that holds it.
You should be able to use a 3/8" or 1/2" ratchet with a 12mm socket. (I only felt it, so I am guessing)
But 12mm seems to be a very common size for Scion and Toyota in general.

The bolt goes through two ears (or lobes) that are part of the engine block. The lobes are on either side of a "tunnel" that is part of the alt's housing. If it is too difficult, try shooting some penetrating oil into the back, where the threads are set into the lobe on the block.
Careful not to spray any into the alt itself.
